Easiest RAID configuration to recover data if ReadyNAS fails
Hello, I have a ReadyNAS 104 and am not able to buy another quickly if mine fails someday (the NAS, not the drives), because I live in Brazil and hardware of this type here is prohibitely expensive...

I see. Thanks for the explanation, I think the VM is a viable option.
Also now I see that I have a problem if I want to go with RAID 6 as you suggested. I already had 2 HDDs (they hold my data now) and bought 2 more (identical) to use with the 104. The new ones are already on it. Originally I planned on copying the data to those two new ones on the 104 and then adding the 2 old ones later, one by one, letting it rebuild. I was wrong on that assumption, since I need 4 drives for RAID 6, right?
Would it be possible to build a RAID 6 or RAID 10 that way? My understanding is that it won't be possible for RAID 6, but could I use RAID 1, copy the data, then add the two other drives and turn the array into a RAID 10 at least? I don't have enough space on other drives to make a backup of it all.
